• When changing the lens, if dust or debris gets inside the camera and adheres to the 

surface of the image sensor (the part that acts as the film), it may appear on the 
image, depending on the shooting environment. The camera vibrates slightly when 
it is turned off, due to the anti-dust function, to prevent dust from adhering to the 
image sensor. However, attach or remove the lens quickly somewhere away from 
dusty locations.

• Do not leave the camera with the lens removed.
